Spindle Cell Lipoma Occurring in the Submandibular Space: Fifth Case Reported along with a Concise Review of the Literature.

Spindle cell lipoma (SCL) is an uncommon histological variant of lipoma that accounts for 1.5% of all adipose tumors. It rarely occurs in the oral cavity.

Histopathological Factors in Oral Squamous Cell Carcinoma-Should a Clinician Look Beyond Clinical Staging?

Purpose: Several researchers have proposed and investigated the prognostic implications of various parameters, but have failed to provide concrete evidence regarding the inclusion or exclusion of histopathological features while clinically managing an oral squamous cell carcinoma (OSCC) case. The study purpose was to measure the prognostic values of a set of key histologic features and its association with its clinical outcome-5-year survival.

Materials And Methods: This is a prospective cohort study and the sample was composed of patients treated for OSCC (April 2014 - March 2015).

Pattern of tumor invasion, stromal inflammation, angiogenesis and vascular invasion in oral squamous cell carcinoma - A prognostic study.

Introduction: Oral cancer is one of the leading causes of mortality, and its worsening impact on the society has revealed the danger it poses in the coming future. Several researchers proposed and investigated the prognostic implications of various clinicopathologic and histopathologic parameters.

Aim And Objectives: The aim of this study--assessing significance of histopathological features like pattern of tumor invasion, stromal inflammation, angiogenesis and vascular invasion on the clinical outcome of oral squamous cell carcinoma any possible correlations between the parameters, TNM Staging and prognosis were assessed and evaluated for a 5-year period.

Intraoral Sebaceous Carcinoma: Case Report of a Rare Tumor Emphasizing the Histopathological Differential Diagnosis.

Background: Sebaceous carcinoma (SC) is an uncommon cutaneous malignancy, usually occurring predominantly in the eyelids and only occasionally involving the oral cavity. Sebaceous carcinoma (SC) is a rare malignancy. Only 10 cases of sebaceous carcinoma of the oral cavity have been reported so far.

Immunohistochemical expression of Type IV Collagen and Autocrine Motility Factor Receptor in Odontogenic Tumours.

Background: Autocrine motility factor receptor (AMFR) is a tumour motility stimulating protein secreted by tumour cells. The protein encoded by this gene is a glycosylated transmembrane protein and a receptor for autocrine motility factor. It has been known to play a role in progression of neoplastic lesions.

A tender swelling of the left posterior mandible: An unusual case.

Tender swellings of the mandible are majorly due to inflammatory lesions like infected dental cyst, peri-apical abscess or neoplasms like osteoblastomas, cementoblastomas, osteosarcoma and intraosseous squamous cell carcinoma. Florid cemento-osseous dysplasia is a subgroup of cemento-osseous dysplasia typically found in middle-aged black women as multiple, non-tender, diffuse, lobulated radio-opacities distributed throughout the maxilla and mandible, which are usually bilaterally symmetrical. Histologically, they are composed of proliferating fibrous connective tissue stroma containing foci of cementum, osteoid and bone.

Alteration in buccal mucosal cells due to the effect of tobacco and alcohol by assessing the silver-stained nucleolar organiser regions and micronuclei.

Background: Oral habits such as alcohol consumption and tobacco chewing are considered to be initiators of dysplastic changes in the oral mucosa.

Aim: The aim of this study was to determine and compare the alteration in apparently normal buccal mucosal cells due to effect of alcohol and tobacco by assessing silver-stained nucleolar organiser regions (AgNORs) and micronuclei.

Materials And Methods: The study comprised a total of 100 subjects which were divided into four groups with 25 subjects having alcohol consuming habit, 25 subjects were tobacco consumer, 25 were both alcohol and tobacco consumer and 25 formed control group who neither consumed alcohol nor tobacco.

Genotoxicity of digital panoramic radiography on oral epithelial tissues.

Objective: To evaluate the genotoxic effects of x-rays on gingival and buccal epithelial cells during panoramic dental radiography using the micronucleus test.

Method And Materials: Eighty otherwise healthy subjects who required a diagnostic panoramic radiograph and met the selection criteria were included in the study. Epithelial cells were obtained from the maxillary anterior gingiva and buccal mucosa by gentle scraping with a wooden spatula immediately before exposure and again 10 days after exposure.

Granular cell ameloblastoma showing desmoplasia.

Our case of ameloblastoma had a surprisingly long 25 year history, with abnormally large dimensions, a multilocular diffuse-mixed radiographic picture, and was histopathologically diagnosed as granular cell ameloblastoma with desmoplasia. To the best of our knowledge, this is the first ameloblastoma ever reported, that has shown combined features of granular cells, desmoplasia, ameloblastic follicles, plexiform, and acanthomatous patterns. The nature of granular cells in this type of tumor and the significance of their presence have also been reviewed.

Primary B-cell MALT lymphoma of the palate: A case report and distinction from benign lymphoid hyperplasia (pseudolymphoma).

Diagnosis of palatal swellings is a challenge. Benign and malignant tumors may be misinterpreted as lesions of inflammatory origin. We present a case of B-cell non-Hodgkin lymphoma on the palate of a 40-year-old male.
